It is known that type 2 diabetes can be broadly grouped into cases driven either by the inability of pancreatic beta cells to make enough insulin, known as insulin deficiency, or by the inability of liver, muscle tissues to use insulin, known as insulin resistance.
A new study by Harvard Medical School researchers based at Massachusetts General Hospital finds that inducing the production of new neurons in the brain structure in which memories are encoded can improve cognitive function in a mouse model of Alzheimer’s disease.
Their investigation shows that those beneficial effects on cognition can be blocked by the hostile inflammatory environment present in the brain of patients with Alzheimer’s disease and that physical exercise can “clean up” the environment, allowing new nerve cells to survive and thrive and improving cognition in the Alzheimer’s mice.
Dr Gregory Curfman of Harvard Medical School and health care policy Says,”Statin therapy in older adults may be associated with an increased mortality rate” , “should be considered before prescribing or continuing statins for patients in this age category”.
The creation of genetically modified and entirely synthetic organisms continues to generate excitement as well as worry.
Such organisms are already churning out insulin and other drug ingredients, helping produce biofuels, teaching scientists about human disease and improving fishing and agriculture. While the risks can be exaggerated to frightening effect, modified organisms do have the potential to upset natural ecosystems if they were to escape.
